Type

EXS API and SwitchKit API message

Description

Outpulse Digits 0x0020

This message instructs the CSP to outpulse up to two strings of digits to the specified channel. The strings may be in BCD or non-BCD format.

Using non-BCD format allows the host to insert silence between the outpulsing of digits by inserting delay digits (0x10) within the digit string. When a delay digit is encountered in a digit string, the DSP providing the outpulsing will transmit silence for the delay duration. The delay duration is configured by the host in this message. Delay digits may be grouped to provide dynamic delay durations.

:

String Mode

This field is valid only if signal type is MFR1. (Set to 0x00 for DTMF)

0x00 The CSP will insert KP and ST framing digits.

0x01 The host will insert framing digits.

:

First Digit Duration MSB, LSB

This field is valid only if signal type is MFR1. (Set to 0x00 for DTMF)

A two-byte field identifying the length of time to outpulse the KP signal.
The typical duration is 100 ms (0x000A).

:

Digit Duration MSB, LSB

A two-byte field identifying the length of time to outpulse the digits.
The typical duration is 80 ms (0x0008).

:

Interdigit Duration MSB, LSB

A two-byte field identifying the length of time to wait between each outpulsed digit.
The typical duration is 80 ms (0x0008).

:

Delay Duration MSB, LSB

A two-byte field identifying the length of time to wait when the delay digit (0x10) is encountered
in the digit string. The typical duration is 40 ms (0x0004); it should not be less than 20 ms
(0x0002). When determining the delay duration, keep in mind that the inter-digit duration will
apply between digit delays.

Generate Event Flag

0x00 Do not inform host when outpulsing complete

0x01 Inform host when outpulsing complete with a Call Processing Event message
specifying event type as "outpulsing complete."

:

String 1 Digit Count

Number of digits in string to follow (0x01–0x64).

This message allows for 100 bytes of digit data which means: if the host specifies string format
as BCD, it may outpulse two BCD strings of length 100 each, and if the host specifies string
format as Non-BCD, it may outpulse one string of 100 digits, or two strings with the sum of
digits in both strings equal to 100.
